Pin Assignment
Sample Application Circuit
*1: When the breakdown protective DI at reverse connection is to be used, it is necessary to insert the capacitor Cr to
secure the regenerative current route. Similarly, Cr must be provided to enhance the reliability when there is no
capacitor near the fan power line.
*2: To obtain Hall bias from VCC, carry out bias to VCC with resister R2 as shown in the figure. Linear driving is
made through voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the
startup performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further.
*3: To obtain Hall bias from the HB pin, carry out constant-voltage bias at about 1.5V, which enables the Hall element
to generate the stable Hall output satisfactory in temperature characteristics. Adjustment of the Hall output
amplitude is made with R1. (When VCC=12V, the step *2 above proves advantageous for IC heat generation.)
*4: Keep this open when not using.
*5: When the wiring from the Hall output to IC Hall input is long, noise may be carried through the wiring.
In this case, insert the capacitor as shown in the figure.
